Hi, First, I would like to ask for your apologize for my very bad english... My name is Frédéric Serrano, I'm a technician and I'm starting my own business. For a new contract my customer ask me to adapt his industrial machine for the USA. So I have to comeback to the basic rule. Here in...

I drink a lot of espresso. From my minimal knowledge of espresso machines, I understand that the water is heated into steam which creates pressure forcing the steam through the coffee grounds. After every batch of espresso I let the machine sit overnight unplugged. Presumably, the water gas...

I have worked out all relevant information (i hope) but I am unsure of how to work out the law of the machine from it. We've done a test and recorded our results of a Pully. We had to measure different loads and see what effort was required for each load. What is the formula for working out the...

Homework Statement Consider a modified Atwood machine, where one mass of 20 kg lies on a flat tabletop, and another mass of 5 kg hangs off the edge of the table, where the two masses are connected to each other by a massless string and a frictionless pulley on the edge of the table. The...

Hi, I am working on a project that involves classifying many 'situations' where there are some number of objects and the objects can be defined by the makeup and weighting of their parameters. There are probably 200-2000 parameters per object, 1 to 100 objects and hundreds of situations...

So perpetual work/motion machines are impossible, but I've toyed with this idea for a hypothetical, super massive, planetary-scale electrical energy generator for a while. Suppose you had 2 very large moon/planet-sized spherical magnets that were far enough so as to not attract magnetically...

I heard many time the word of Time Machine. Can the concept of Time Machine become true in future? what is your opinion...?

1 - I'm trying to see what's the difference between a Turing Machine and a universal Turing Machine. Aren't the same? 2 - If I have a Touring Machine that to solve a problem, for example, adding numbers, what is the purpose of a Universal Touring Machine?

I recently purchased an old small drill press. It hosts a retasked old washing machine motor as the power source. Only problem is that the wiring was snafu, and I could use some help with that. This is a FSP motor, 115 volt 1725 rpm, 1/3 horsepower. The motor input wiring are to a set of...

In the Turing Machine, the machine accepts a word if the computation terminates in the accepting state. The language accepted by the machine, L(M), has associated an alphabet Δ and is defined by L(M) = {w \in \Delta} This means that the machine understands the word w if w belongs to the...

Basically we did a lab where you attach a pulley to the desk with a clamp and then have a friction block (three types: cork, plastic, and felt) attached to a string which is attached to a hanging mass. This basic setup is called an atwood's machine. The purpose of the lab was to identify the...

Hello I am trying to start a small home business making soap. I am on a really tight budget and also very new to the extrusion process. While I may be extruding soap, I understand that the process is very similar to plastic extrusion. I want to extrude soap bars using a machine...

Homework Statement I'm trying to find the acceleration of the masses in an atwood machine, the pulley has a rotational inertia I. The pulley has a radius R Picture : http://en.wikipedia.org/wiki/File:Atwood.svg But I made it accelerate the other way, so the equations from Newtons 2nd law are...

I'm thinking of taking machine language over the summer because it seems interesting to me but I'm not sure if it'll be useful to my emphasis in computational physics. The objectives of the class are below, could anyone give me advice on whether it'll be helpful to me or not. Thank you. A...

Simple enough - I'm just trying to find the smallest positive real number, ε, such that 1 + ε ≠ 1 in MATLAB (double precision). So the value 'eps' in MATLAB is actually not quite defined this way, and using this program min = 0; max = 1; test = 1; while test~=(min+max)/2 test =...

I'm currently taking a Microprocessor course and we are adding to our breadboard week by week. The most recent add on was a UT6264CPCL RAM chip. Other chip specifications are given below in in 2. Homework Equations . My question is, how do we test to make sure that the RAM is working using two...

I need to build a rube goldberg machine for physics class and i am stuck on ideas. It must include circular motion, projectile motion, rolling motion, gravitational energy, kinetic energy, elastic enrgy, conservation of momentum, and electric or magnetic fields. It cannot be powered by more than...

Now I'm not a PMI (perpetual machine inventor). In fact I'm quite convinced that there is no such thing as that. But a while ago, I saw the schematics of a perpetual machine that is hard to debate. Well this is how the machine worked. The inventor argued that if you have two magnets as...

Hi all, You have probably seen these candy machines before. Tubes that contain candies of different colors and drop candies into a receiver once you inserted the coin. I was watching these more than a quarter of an hour at lunch time (waiting for someone to buy candy) and thought that...

Hello, I am in Grade 12 physics class and I have been given a open ended project; where we are required to build/create a machine which would involve at least 6 of the physics concepts: ramps, pulleys, levers, transfer of momentum/energy, projectile motion, circular motion, stored elastic...

Homework Statement Consider Atwood's machine with two masses, m1 and m2 with m1 less than m2. Now, according to application of Newton's third law, the system accelerates in the direction of the heavier mass (here, m2). This, however, seems to contradict Newton's third law, which implies that...

This seems to be the new 'it' job in the tech sector and I'm considering getting into this line of work, but because it seems relatively new I'm having trouble finding out what it's like to work as a data scientist. The two things I'm somewhat concerned about is if the work is interesting or...

Homework Statement I have a modified atwood machine which is made up of a vertical mass hanger (hanging over the side of a table) connected to a horizontal cart (on the table) via a rope (un-stretchable) and a pulley (massless, frictionless, etc). The cart wheels have negligible friction...

1. I am trying to figure out the equation for tension force, friction force, acceleration, it looks from my very little physics knowledge is that it is based on the Atwood Machine, not the free hanging Pulley, but the pulley with the table (where one block is hanging, one is flat on the table)...
